Problems solved by technology

[0003] The above method requires color separation and protection of the topcoat in the area to be sprayed and the surrounding area before formal spraying, and regardless of the size of the area to be sprayed, as long as there are multiple colors in the area to be sprayed, each color must be protected one

Example Embodiment

[0023] Example 1

[0024] In this embodiment, the subway car door of Line 5 is used as the object of partial topcoat color separation spraying. In order to ensure the straightness of the connection between the door ribbon and the car body ribbon, the door color separation is performed after the car body is assembled. The door ribbon and the car body ribbon have the same distribution. If the traditional color separation method is used, the operation cycle is the same as the car body color separation cycle, which will delay the production cycle.

[0025] The partial topcoat color separation spraying method of this embodiment is specifically as follows:

[0026] 1. Set the color separation tape

[0027] Perform color separation on the door according to the artwork, that is, separate color separation tapes around the edges of multiple areas to be sprayed on the door, so as to divide the color separation boundaries of the areas to be sprayed.

[0028] 2. Set up the bracket

[0029] Cut out m...

Example Embodiment

[0035] Example 2

[0036] In this embodiment, a small area containing multiple colors to be sprayed is used as a partial topcoat color separation spraying object, and the partial topcoat color separation spraying method is specifically as follows:

[0037] 1. Set the color separation tape

[0038] Color separation tapes are respectively enclosed at the edges of multiple areas to be sprayed in a small area, so as to divide the color separation boundaries of the areas to be sprayed.

[0039] 2. Set up the bracket

[0040] Cut out multiple sections of protective tape with a width of 50mm, and fold them in half along the length (the side with adhesive faces outward), and surround one side of the two sections of protective tape folded in half on the outside of the area to be sprayed (such as pasting Fixed in the area where the color separation tape is located), the other side is pasted to each other to form a bracket, which is vertically arranged on a small area with a height of 5 cm.

Abstract

The invention provides a color separation spraying method for partial finish paint. The color separation spraying method sequentially comprises the steps of arranging color separation adhesive tape on the edges of a plurality of areas to be sprayed in a surrounding mode; arranging vertical supports outside the areas to be sprayed in a surrounding mode; protecting the exterior areas of the areas to be sprayed; spraying the areas to be sprayed; and drying the areas to be sprayed after the areas are sprayed. The color separation spraying method for the partial finish paint has the advantages that the operation is easy and fast, the applicability is high, the operation time can be shortened on the premise of guaranteeing the product quality, and the operation efficiency can be improved.

Description

technical field [0001] The invention relates to a coating method, in particular to a color-separation spraying method of a partial topcoat. Background technique [0002] The topcoat is the final coat of paint, and multiple colors in one area may need to be treated during the topcoat application or rework process. At present, the method of color-separation spraying of partial topcoat is to separate the color of the area to be sprayed according to the spraying sequence of the color-separation topcoat according to the art plan and technical requirements. After retaining the sprayed area of ​​the first color and protecting other areas, the The spraying area of ​​the first color is sprayed with topcoat and forced to dry. After the topcoat of the first color is completely dry, the next area to be sprayed is protected again, and the spraying area of ​​the second color is reserved and other areas are protected. For good protection, spray topcoat on the sprayed area of ​​the second ...
